  • Merlin Series M3 pumps require a 4” or larger well casing

  • KS02 system requires a 2 3/8” OD pole
  • Flows decrease as depth and pressure increase to maximum depth of 90 feet (39 PSI)


No additional controller is required for API solar water pumps, however the ALC 1275 greatly increases the life expectancy of our stainless steel pumps and prevents unnecessary wear and tear on the pump.

150 and 200 feet wire rolls are available. There is a $35.00 up charge for each additional 50 feet of wire.

Please be sure your well has been tested for flow rate and continuous flow supply. In order to reach these water demands, your well must be able to keep up with the solar pump. Otherwise, damages can occur.

  • Do you have wind turbines within 1/2 mile of your solar pump system? Find out why your system can become damaged here.
  • Don't forget to prep your system for the winter!! Weep holes are a must!
  • Ground Rods are great for preventing damage from lightening strikes, we highly recommend ground rods for solar systems.
